This invention relates to a device for lubricating the rings and travelers of ring spinning and twisting frames, and more particularly to lubricating devices of the kind having a lubricating wick which is provided in an annular groove in the inner bearing face.

In these lubricating devices it has been proposed to provide a slot in the ring converging to.- wards the inside of the latter, and to press into this slot a fiat and straight wick composed of felt or the like which is moved past the ring. This wick, however, when saturated with oil, readily tends to swell and is forced into the said converging slot and compressed, the passage of the lubricant thereby being adversely affected and the lubrication being irregular and deficient. Moreover, owing to local heating, the edge of the felt directed towards the bearing face of the ring acquires a resinoid character and then permits of the passage of little or no oil at all.

It is the object of the invention to overcome these disadvantages, and with this object in view the wick fitted in the tapered slot is so constructed that it is merely weakly compressed without being able to pass through the slot to such extent as to jeopardize the operation of the traveler. To accomplish this object the strip of felt extending into the slot is furnished with wedgeshaped incisions which, when the strip of felt is pressed into the slot, allow the single webs of felt between the incisions to yield laterally so that they will not be compressed, but will continue to convey oil as before. Moreover, since the edges of the incisions do not touch each other, but remain fully exposed, the passage of oil is readily permitted also at these points, this oil being picked up by the suctional action of the traveler against the inner face of the ring. Since the wedge-shaped incisions are not subjected to heating under the action of the moving traveler, the edges will not become hard or assume a resinoid character, so that a sufiicient supply of oil will be ensured at all times.

The invention is illustrated by way of example in the accompanying drawing, in which Fig. l is a longitudinal section taken through a ring rail,

Fig. 2 being a plan view of the same.

Fig. 3 is a section taken along the line III-III of Fig. 2, whilst Fig. 4 is a section along the line IV-IV of Fig. 2.

Fig. 5 shows, partly broken away, a modified form of the covering means for the wick channel in the ring rail.

The rings I may have the conventional crosssection and be of any desired size. These-rings I, on which there rotate the travelers 2, which may beof any desired form, are fitted in open.- ings 3 in the ring rail 4, and are secured in position for example by means of screws 5.

In the ring rail 5 there is provided a fiat channel I5, into which there may be fitted a fiat wick I. This wick I projects with the one edge into a slot 8 in the ring I, this slot converging towards the inner bearing face 9 of the said ring The length of the slot 8 amounts to between one-fifth and one-third of the circumference of the ring, dependent on the desired degree of lubrication.

On the outside of the ring I the width of the slot 8 is approximately equal to the thickness of the flat wick I. At the bearing face the slot 8 is approximately 15 to less in width.

If the wick is passed in the ordinary way through the channel 6, it is pressed together in accordance with the curvature of the ring I and fits tightly into the slot 8 without projecting beyond the inner bearing surface. At the same time there is a, considerable degree of compression of the wick, which obstructs the passage of the lubricant. This drawback may be overcome by constructing the wick in accordance with the curvature of the ring, for example by adapting the wick to the form of the ring at the points of contact with the ring by cutting away certain sections or adding an extra portion.

In accordance with Figs. 1 to 5, the wick is furnished at the points at which it is conducted past the rings with an arcuate recess Iii (Fig. 2). As a result the wick is compressed merely very weakly, so that the passage of the lubricant is not adversely affected. The desired effect may also be enhanced by furnishing the arcuate out In with incisions I I. In this way the wick when the same is pressed into the tapered slot 8 is able to expand in the longitudinal direction thereof, so that no appreciable compression of the wick 1 takes place at all.

According to Figs. 1 to 4, the wick is introduced into the flat channel 6 provided in the ring rail. The channel 6 is closed by a cover I2, which is connected firmly with the ring rail 5 by means of screws I3. In the cover I2 there is provided a longitudinal channel It for the distribution of the oil. This channel It posesses enlargements I5 (Figs. 2 and 4), which are capable of accommodating a comparatively large quantity of lubricant. There are screwed into the ring rail at spaced intervals oilers I6, below which the wick is furnished with perforations I], so

that the oil is able to pass to the channel l4 and fill the enlargements or chambers (5.

In place of the cover [2 bridging the channel 6 there may also be provided a liftable cover I8, which is capable of being lifted about a hinge l9 and is secured to the ring rail for example by means of the screws 20. In this case there are provided in the wick 7 a plurality of openings 2|, into which the lubricant may be filled and thus distributed over the wick.

To be able to supply the lower and outer bearing faces of the ring with oil, small borings 22 pass to the lower face from the slot 8. In addition to these' borings, or alternatively thereto, grooves 23 may be provided for conducting the lubricant over the face 9 (Fig. 3).

What I claim as new and desire to secure, by Letters Patent is:

1. In a device for lubricating the rings and travelers of ring spinning and twisting frames, a fiat channel provided in the ring rail, and a wick fitted in the said channel and projecting with its one edge into a slot in the ring converging towards the inner face of the ring, the said wick in the said groove being cut to form a plurality of wedge-shapedspaces into which the fibre of the wick may move when it is compressed by the converging faces of the said slot. 7

2. In a device for lubricating the rings and travelers'cf ring spinning and twisting frames, a fiat channel provided in the ring rail, a wick fitted in the said channel and projecting with its one edge into a slot in the ring converging towards the inner face of the ring, a cover for the said channel, and passages and compartments in association with the said channel for storing and distributing the lubricant, the said wick being so shaped as to conform substantially to the form of the said ring and being cut to form a plurality of wedge-shaped spaces into which the fibre of the wick may move when it is compressed by the converging faces of the said slot.

3. In a device for lubricating the rings and travelers of ring spinning and twisting frames, a flat channel provided in the ring rail, a wick fitted in the said channel and projecting with its one edge into a slot in the ring converging towards the inner face of the ring, and oilers screwed into the ring rail above perforations provided in the said Wick, the said wick being so- WILLY KoHLER.
